Xiaomi phones have a problem with dual sims. if data is on in one sim then the other sim cant make or receive calls. Also most of the times it’s really hard to get good call reception when 2 sims are used.Xiaomi has incorporated a one-handed mode, which you can enter or exit by simply swiping right from the capacitive Home button. You can even choose the size to which you want the display to shrink. The phone comes with a preloaded app called Mi Mover which lets you move apps and data to or from any other Android device. MIUI 7 supports up to 13 indic languages. Apart from the standard Google keyboard and SwiftKey, our test unit also had a keyboard called Fleksy, which turned out to be much better than we had expected.
